Title: Apparatus for indicating injection timing and fuel per stroke in an internal combustion engine
Inventor: SUNDEEN ARTHUR ROLAND
IPC: F02B3/06
Filed: 1982-07-27
Abstract: Apparatus for indicating timing and fuel/stroke in a pulse fuel injection system for an internal combustion engine, especially a diesel engine, includes a magnetic piston 40 axially movable in a cylindrical bore 37 in a fuel line to and from a stopped position blocking an inlet 38. The piston 40 is included in a magnetic circuit including an actual coil 46 having an inductance varying with piston position. Circuitry provides a DC current pulse to the coil 46 prior to injection to move the piston 40 to its stopped position and then provides an AC current to the coil and monitors the voltage and rate of change of voltage thereacross. Change of voltage past a first reference is sensed to generate an injection timing signal; and decrease of rate of change of voltage past a second reference with voltage past the first reference triggers sensing of the voltage as a signal indicating fuel quantity per injection stroke. <IMAGE>
